The hoisting winch of a mobile crane is driven by two hydraulic
motors connected to a common drive shaft. A control system for the
motors includes manually controlled directional and speed control
valves. The speed control valve optionally connects the motor
hydraulically either in parallel for low-speed, high-torque
operation or in series for high-speed, low-torque operation. A
speed-limiting feature automatically shifts the speed valve to or
maintains it in its low-speed position whenever the load is too
heavy to be handled by the system in its high-speed mode. The
hydraulic circuit of the control system also provides
anticavitation protection for the motors when in its high-speed
